Appiic'ationifiiea March' 12,1927. seran No. 174,792.-

The object vof the invention is to provide improvements inhinges, andparticularly in thaty classwhich is employed as ak means ofpivotallysupporting the doors and case-` ment sash of house, 'the doorsof an en* closed porch, the doors andsash of aV oo n-y servatory, etc..

The types of hingesusually found .onthe market merely comprise a`pair-of plates, each .of which is provided With a. plurality of spacedcylindricall-y curvedknuckles, and

so arranged When the platespareuin operative relation-,that theknucklesof the respective plates alternate, and provide an aligned borethru Which extends a pinzfor removably connecting the plates togetherand 'in pivotal relation., 1 i i c A l nge of this character permits thevdoor which it supportsfto remain in any position to which it ismanually propelled, but doesy not preventV the door-Strom being blownk{u1-ther Vopen or closed 'byl @V611 a. Slight" breeze, so that'anotherobject'of the inventionis to .provide broadly a liingewhich Will rretain adoor iii any oneorn aseries oit diti"erent angular posi-tions,until the nicchianisin of the hinge is released', attervvhich saidinechanisminaybe set in operative'position, or' again set to hold thedoor in `some other position Awhich is-fangularly disposedl with respectto the first.` l

A further obj ecto-il thel invention is tofpro# vide in aliinge otthistype acoiistruction which comprises a 'suitably notched knuckle,

anzadjacent,fknuckle ofthe-other plate of' "receivethe nusual screw's'bywhich the lhinge l the vpairbei-ng recessed to ormma spring housing inwhich is; inclosedfa spring, 'and a cylinderpositioned within saidrecess'an'd liavingjonegend*notched to: cooperate; with' the saidnotches of said first knuckle.

V,Still another object isto provide the re? cessedvknuckle 'of thiscombination With a Tf shaped, aperturethru which extends apin,

Y the inner portion of which latterv isl con nectedV to saidlcylinderand is thereby opper-y ative to shift*` the axial position of said ,cyl

inder by engagement from the outer side of said apertured knuckle.

. And a still :further object to provide af sleeve surrounding saidapertured'knuckle manual actuationv of thel latter and tovcover e saidaperture, said sleevelhavinga cut-away region thru which y extends, :thesupporting Ori baS ii C-1UOHO.Sallaieitufd fkmwkei yYiith theseandjot-herr ob] ects'n inwiew, lthe -'ront 'elevation fajhinge of theinventionvcoinprises further details of yconstruction and operationhereinafterV` fully brought outv in the following desoription,

Theplate 10 is provided with extensionswhichy `are cylindricallyf curvedtoprovide spaced knuckles 13, `Whilethe plate -ll isprovided With similarknuckles lll, normally,positionedaxially between said first-named knuckles. Through these Several axiallyaligned knuckles there normally `upon saidfraine lby,means oftheimproved ing novvfto '.Figs. '2 toinclusive', l'

the lower wall of each oil-set being pieten.

ably separated from the adjacent walls of the portion 1S by means ofslightly upwardly extending shoulders 20.

Slidably positioned Within the bere 1G oi said knuckle 13 is acylindrical member 2l` provided at one point in its Wall with a threadedaperture 22, and having its lower most end portion radially cut toprovide circui'niierentially spaced notches to provide interveninglugs23. A coil spring 241 or thev like is also positionedwithin saidbore between the upper edge portion of the cylinder 21 and the shoulder17 and is operative to iorce said cylinder downwardly, in which positionits lugs engage and cooperate with similarly shaped circumierentiallyspaced recesses 25 formed in the uppermost surface of the knuckle 14rimmediately 'therebeneath- A threaded pin or bolt 26 has its endextend- I ing through and in threaded engagement with the aperture 22 inthe member 21, whence'said bolt extends radially outwardly through theT-shaped aperture in the knuckle 13, and thence through a sleeve or'ierinle 27 which substantially surrounds said knuckle 13, exceptior acut-away portion 28 which places the'circumferentially extending ireeend portions of said sleeve in spaced relan tion from the plate 10 atits point of connec'tion with said knuckle, as shown in Fig. 3.

In the operationoi Vthis device, even though the parts involved aregenerally much smaller than illustrated in the drawings, one canvmanually grip thesleeve 27 with his lingers and after raising the sametogether with the cylindrical` member 21,

rotate these conjoined elements in either direction until 4said pinpasses over one ofthe shoulders 2O in the lshaped slot,and rests withinthe corresponding lateral extension 19 oi said slot; 1n this positionthere is no engagement between the lugs oi the cylin' drical member andthe corresponding recesses of the nether knuckle 14 and as a re,- sult,a door equipped with the hinge is iiee to be oscillated to and froat-will. However,

' 1 when it is desired to open the door to a given position, one gripsthe sleeve 27 and, raising it slightly against the pressure oi thespring 211, rotates said sleeve until the pin 26 passes over theshoulder 20 and isk thereafter adapted to descend in the verticalportion 18 oit said aperture, and under the ine iiuence oit' said springcause an engage-ment Y of the lugs of said cylindrical member with therecesses of said nether hinge knuckle 1K1. In this position therespective hinge plates and consequently the door and frame connectedthereto are'retained in a given position from which they can beoscillated onlyA by ist raising the sleeve 27 and disengaging the seriesoi said lugs from the corresponding recesses.

Having thus described my invention, what .l claim and desire to protectby Letters Patwith the sides or said recess, and means extendingradially beyond the diameter of said bore to manuallyy shift'saidcylindrical member longitudinally, to disengage said lug from saidrecess. y s

2. A hinge-,comprising a pain of plates provided with alternatelypositioned axial` ly aligned cylindrical knuckles, one oi said knucklesoi one plate` having an enlarged bore terminating in'a shoulder in onedirec'- tion, a cylindricalmember provided with a lug and longitudinallyslidable wholly with-k in the diameter o1' said bore, an adjacentknuckle ci the other plate having'a recessV adapted to receive said lug,means operative yto maintain ysaid lug in engagement with the sides ofsaid recess, means connected to said cylindrical member and extendingradially thru an aperture in said large-bored knuckle, and a sleevesurrounding and oscil- .latablewith respect to' said last-named knuckleand connected 'to said means, whereby'elevation oi said sleevedisengages said lug from said recess.

3. The combination oi a hinge, compris! ing a pairo plates havingalternatelypo` sitioned axially alignedl knuckles, a knuckle oi' oneVplate having an enlarged' boie terminating in one' direction in Vashoulder, cylindrical member slidable longitudinally in and oi nogreater diameter than the diameter oi said bore and provided upon oneend 'with spaced lugs, an expansion spring also within said bore betweensaid member and said shoulder, an adjacent knuckle oi the other platebeing provided with spaced recesses adaptedto receive said lugs, asleeve surrounding said iirst knuckle, and a pin extending between andconnected to said sleeve and said member, whereby eleif'ation oi saidsleeve removes Vsaid member` A125 and its lugs out on engagement withSaid' recesses.
